FENCE-POST.

SPECIFICATION forming part of Letters Patent No. 303,263, dated August12, 1884-.

Application filed August 4, 1883. (No model.)

To all whom it may concern:

Beit known that I, Annon B. BURTON, of the city, county, and State ofNew York, have made and invented certain new and useful improvements inFence-Posts, of which the fol-' lowing is such a full, clear, and exactdescription as will enable others skilled in the art to make and use thesame, when taken in connection with the accompanying drawings, in whichFigure 1 is a front view showing cross-section at top of post built upof four pieces of angle-iron riveted together, and having insertedbetween the angle-irons, near the lower end, extension-webs; Fig. 2, across-section of Fig. 1 as at a b,- Fig. 3, a front view showing crosssection at top of postbuilt up of two pieces of T-iron riveted together,and having inserted between the T-irons, near the lower end,extension-webs; Fig. 4, a cross-section of Fig. 3 at c d,- Fig. 5, afront view showing cross-section at top'of post built up of three piecesof angleiron riveted together, and having inserted between theangle-irons, near the lower'ends, exsion-webs. Fig. dis a cross-sectionof Fig. 5 at ef.

This my invention relates to posts having screw-flanges at or near thelower ends; and it consists in forming these posts of two or more piecesof angle-iron riveted together so as to form the flanges, and thevarious combinations hereinafter specified and claimed.

Angleiron of various forms in cross-section may he twisted so as to formscrew-flanges thereon; but it is not necessary to describe them.

The post shown in Figs. 1 and 2 is built of four pieces ofright-angleiron riveted together. The pieces of right-angle iron A A A A are heatedand twisted so that a screw form is given to the portion at or near oneend, and the several adjacent pieces are then riveted together so as toform a solid post. In order to increase the bearing-surface withoutmaterially adding to the expense or weight of the post, I introduce inthat portion of the post where the screw is a flange or wing, B B B ll,between each of the adjacent anglepieces, and rivet through theanglepieces and wings. These Wings may be of greater or less size,according to the nature of the ground they are to be used 'in and theweight they are to sustain. The wings B may be introduced on only twosides, if desired, and will be found to give good results.

The post shown in Figs. 3 and 4 is built up by riveting two pieces ofT-iron, K K, together by the flanges at the top of the T, one end ofeach piece of the T-iron having been heated and twisted into a screwform. Between the T-pieces may be placed a plate, L, of greater widththan the top of the iron, and of corresponding screw curve with theT-irons.

The T-irons K K and plate L are riveted together, so that the plateforms wings or flanges.

The post shown in Figs. 5 and 6 is built up by riveting three pieces ofobtuse-angle iron, M M M, together by rivets through their adjacent websor flanges, one end of each piece of the angle-iron having been heatedand twisted into a screw form. Between each of the adjacent flanges maybe inserted apiece of iron, 0 O 0, having a screw GHIVG correspondingwith that given to the end of the angle-irons M, and the riveting isdone through the adjacent flanges of the angle-irons and the plates 0 O,and the several parts may be fastened to gether straight before twistingthem, andthen be heated and twisted without departing from my invention.

The posts are sh own with the additional pieces or wings. These,however, may be omitted, as the flanges of the angleirons are sufficientfor many purposes.

Among the advantages of a post formed as above described are thefollowing: greater lightness for the strength, greater stability,greater bearing-surface for the metal used, and less displacement ofsoil in entering the ground.

I have described my invention as pertaining to fence-posts. It isequally applicable to piles for docks, foundations, or like uses; and Ihave described it as made of iron. The same may I 2.
